Description

 The invention relates to a KARAOKE mobile system that allows a singer or singer to play a vocal part to musical accompaniment recorded in a removable cartridge, and which transmits the singer’s performance and recorded music wirelessly to a receiver.

 It is well known that a modern device for musical accompaniment, usually called the KARAOKE system, will be set up so that by means of an electronic sound system to reproduce the words of a song performed by the singer in front of the microphone, together with the recorded musical accompaniment.

 The usual KARAOKE system includes a player on magnetic tape or discs to play back musical accompaniment of songs. A person can have fun playing a selected song while mixing his voice through a microphone with reproducible musical accompaniment. KARAOKE systems are becoming popular with many people who want to perform songs to the accompaniment of the selected music to improve their performing skills.

 Currently, many restaurants and bars organize special KARAOKE evenings and establish an additional mark-up for visitors, increasing the fee either directly or indirectly, increasing the price of alcoholic drinks, for the right to participate or just to see how other visitors use the KARAOKE system.

 A typical KARAOKE system used in many restaurants and bars includes a microphone, a broadband stereo system with a powerful amplifier that allows you to mix sounds, an echo generator to improve the sound quality of the singer’s voice, a separate control device that provides the singer or singer with a choice of song and synchronization with it, the degree of amplification of the microphone and music, the tempo and pitch of the sound from the place where he or she stands, and provides a fairly wide selection of tunes.

 In such a system, the microphone and the control device send signals through a wired connection to the stereo system, which reproduces the selected accompaniment melody mixed with the performer’s voice appropriately processed by the stereo system. Due to the limited amount of data on a tape recorder or disk, these KARAOKE systems require the participation of a third person, for example, a bartender in a bar, to install accompanying music into the stereo system selected by the singer from a large list of tunes.

 Some KARAOKE systems also contain television monitors for displaying the words of a song so that the performer can read the words during the performance [1].

 It is possible to build a KARAOKE system for home use if a person can combine all of the above components in one place. However, the acquisition of each component will be very expensive for individual use.

 The usual KARAOKE system is also very cumbersome if you take into account the components of the music repository to ensure the selection of a sufficiently large number of songs, a stereo system with a power amplifier for complete and efficient mixing of sounds and a separate control unit. The dimensions of the equipment and the number of its elements make it difficult to transport, and the power requirements make standard connection necessary for most types of equipment. This imposes severe restrictions on the conditions for using the KARAOKE system.

 Another desirable area of use of the KARAOKE system is related to the needs of many young people to choose songs and sound power when driving a car. There is the possibility of connecting the necessary: components of a typical KARAOKE system to the car stereo. However, it is not easy to transfer such a system from one car to another. In addition, a microphone or music storage can work with one system and cannot work with another.

 Another desirable area of use of the KARAOKE system is to conduct street performances, festivals, picnics outside the city or on the beach, but again the dimensions of the equipment and its components necessary to select the desired melody and sound power make this use difficult.

 In addition, many homes have more than one KARAOKE system. Usually in such a house there may be a main system, contained separate independent KARAOKE systems connected by wires. Such a system is usually located in the room where guests gather - a living room or a living room. There may also be an additional KARAOKE system, containing all the components of the system, housed in a large external enclosure. In particular, when there are too many guests who are difficult to place in one room, it is advisable to have two systems for singing in different rooms of the house where there are KARAOKE systems. However, this leads to a significant amount of wiring work for two or more systems, and different systems usually do not have installation tools that provide the ability to play performances in one system so that it can be heard through another system. In addition, it is desirable, when using two systems, to combine the power supply of the systems in one room. However, in this case, there is significant duplication of wiring for two or more systems, and different systems usually do not provide means for combining the power supply of the two systems.

 Thus, there is a need for a system that can overcome the limitations of existing systems related to the dimensions, power supply and requirements for individual components, have the flexibility to use two closely spaced systems, and allow the KARAOKE system to be moved to any place where a person is without any restrictions on location.

 The cost of such a system should also not be excessively high so that users have the opportunity to purchase it at a reasonable price for home use.

 Limitations are overcome in a portable music system for KARAOKE, which contains a storage device with an interface connector for connecting cartridges with music, a search tool for music with a decoder, a radio microphone and a device for converting and processing input and playback music and its subsequent transmission to the receiving device [ 2].

 In the known portable music system for KARAOKE [2], the storage device is a ROM - a permanent storage device for storing music data and their corresponding numbers in the form of digital signals. The musical accompaniment search tool with a decoder comprises a microprocessor for executing predetermined operations in accordance with a program stored in the microprocessor internal memory when receiving input signals from the switch matrix and for selecting music data stored in the memory by the multiplexer and decoder.

 PES in the well-known portable music system for KARAOKE provides storage for up to 1200 songs. By connecting cartridges with musical accompaniment through the interface interface connector, the performer has the opportunity to choose his musical accompaniment from a large list, not limited to the original version of the music stored in the system. Cartridges with music recorded in them are free to sell, so users can purchase music they like and share it with friends to expand their choices.

 Cartridges providing digital recording for storing music data are known [3].

 A cartridge for a portable music system may include read-only memory for storing music and an interface connector for connecting to a music device [4].

 A disadvantage of the known devices - a portable music system for KARAOKE [2] and a cartridge for a portable music system [4] is the insecurity of the data stored in ROM representing the recorded music from unauthorized use, which leads to a violation of the rights of authors of recorded music and legal owners intellectual property.

 Known portable music system for KARAOKE and a cartridge for it, which partially solved the problem of protecting data representing recorded music [5].

 In the well-known portable music system for KARAOKE, containing a storage device with an interface connector for connecting cartridges with music, a search tool for music with a decoder, a microphone and a device for converting and processing the input and reproduced music and its subsequent transmission to the receiving device, an additional a decoder for interacting with the cartridge through the interface connector. At the same time, a cartridge for a portable music system containing a read-only memory for storing music and an interface connector for connecting to a music device is equipped with a key encoder associated with a read-only memory configured to interact with an additional decoder of the portable music system through an interface connector .

 At the same time, however, there is a problem not only of protecting the data contained in the cartridge from unauthorized access, but also the problem of preventing illegal mass production and use of cartridges and other information storage devices containing, in essence, pirated copies of a musical work. The availability and relative cheapness of high-capacity memory microcircuits in recent years have exacerbated this problem, especially in connection with the advent of portable KARAOKE music devices made in the form of a radio microphone.

 There was also the problem of ensuring the electromagnetic compatibility of the “KARAOKE radio microphone” with broadcasting and service communication transmitters operating on the air, as well as systems sensitive to radio emission. On the one hand, to facilitate the use of consumer radios with the VHF-FM range, it is desirable to receive a radio signal at a carrier frequency belonging to the range 67-108 MHz. On the other hand, powerful broadcasting transmitters operate in the indicated range, so that the signal from the “KARAOKE radio microphone” at these frequencies should be powerful enough to be received at an acceptable signal-to-noise ratio, but, however, it should not create interference to broadcasting and should not be received by those listeners who only accidentally ended up in the area of operation of the "KARAOKE radio microphone". There are also legal restrictions on the registration and use of any radio-emitting means using such ranges.

 Thus, there is a need for a system that, being mobile, and therefore wireless, would ensure the exchange of information between transmitting and receiving means, without creating interference on the air.

 The present invention is aimed at solving the above problems and allows, on the one hand, to ensure reliable and high-quality reception of information from the KARAOKE transmitting device, and on the other hand, it allows to eliminate the unwanted effect of the KARAOKE signal on random listeners, to exclude unauthorized access to protected information containing music in the form of authorized data, and also allows to achieve compliance with the legal copyright of the creators of musical works, property rights of intellectual property owners, you can increase the "civility" of music and entertainment industry market.

 To solve these problems in the present invention used a systematic approach. Firstly, measures have been taken (and appropriate technical solutions have been developed for their implementation) to eliminate unwanted radio emissions from the KARAOKE transmitting device. Secondly, the channels of information exchange — optical and ultrasonic — that were not previously used in such systems are proposed. Unlike radio waves, such channels have the ability to easily and conveniently limit their coverage, which prevents the transmission of confidential and / or protected information to those receivers that are not among the invited consumers of such information. The problems of electromagnetic compatibility of radio transmitting and receiving and / or radiosensitive systems are greatly facilitated.

 Unlike the radio channel, the background (noise) component of the signal is almost completely absent in the ultrasonic acoustic communication channel in the human environment, which is due to the absorption of the ultrasonic signal in the air at high frequencies of the signal carrier. Thus, various ultrasonic transceiver systems spaced in space, in contrast to radio systems, practically "do not interfere with each other."

 An additional technical result from the use of the ultrasonic communication channel of the transmitting device with the ultrasonic radiation receivers, namely in the KARAOKE system, consists in the possibility of obtaining new sound effects related to the fact that the ultrasonic signal allows the use of the natural acoustics of the room, the room, to obtain a "presence effect" even when listening to the artist through the headphones. Another technical result from the use of an ultrasonic communication channel consists in the possibility, by selecting and / or adjusting the carrier frequency of the radiation, to control the radius of the device, to prevent reception of the signal by listeners of other programs and / or performers, to use, with a positive technical result, the properties of the ultrasonic communication channel that are still pores were considered its shortcomings (low, in comparison with electromagnetic waves, propagation velocity and a sharp increase in the attenuation of ultrasound s waves in air to increase the carrier frequency of ultrasonic signal).

Thus, the first subject of the present invention is a KARAOKE mobile system, comprising:
- mobile wireless transmitting device,
- a lot of authorized legal cartridges with music data recorded in them,
- a mobile means for receiving a signal emitted by a transmitting device,
- a mobile means for converting the received signal into an acoustic signal,
moreover, the mobile wireless transmitting device has a housing adapted to conveniently hold, move and control the performer, inside or on which are located a microphone for receiving an input acoustic signal, a control panel, a microprocessor, a sound synthesizer associated with a microprocessor, a search tool for musical accompaniment about a decoder, a memory a device connected through a multiplexer with an interface connector for connecting one of the many cartridges, made in the form of a lodgement or molds, means for convenient input and mounting on a cartridge that can be connected via an interface to a cartridge, a device for converting and processing a signal from a microphone and a signal of reproduced musical accompaniment, means for generating a resulting output electric signal and its subsequent transmission in the form of modulated radiation into the surrounding space, an additional decoder for interaction with the cartridge through the interface connector, configured to recognize authorized legal an cartridge that is protected against unauthorized access by an authorized key encoding device with an access password to prevent the mobile wireless transmitter from working with an unauthorized and / or illegal cartridge or other storage device that does not have an authorized key encoding device with an access password and can exchange information with an authorized legal cartridge with an information exchange rate not lower than in real time;
at the same time, in each cartridge belonging to the aforementioned set of authorized legal cartridges with musical data recorded in them, there are installed interconnected and about the interface connector of the cartridge chip of a permanent storage device for storing recorded encoded data, musical accompaniment, and an authorized key identifying and encoding device with an access password to prevent unauthorized access to data stored in permanent storage cartridge device and for identifying cartridge belonging to said plurality.

 The first particular case of such a system is the KARAOKE mobile system described above, in which the mobile wireless transmitting device is configured to transmit a modulated optical signal, and the mobile means for receiving the signal emitted by the transmitting device is made in the form n, where n≥1, an integer number of optical radiation receivers .

 The second particular case of such a system is the KARAOKE mobile system described above, in which the mobile wireless transmitting device is configured to transmit a modulated acoustic ultrasonic signal, and the mobile means for receiving the signal emitted by the transmitting device is made in the form n, where n≥1, an integer number of ultrasonic receivers radiation.

 The third particular case of such a system is the KARAOKE mobile system described above, in which the mobile wireless transmitting device is configured to transmit a modulated radio signal in the first frequency range, selected to provide electromagnetic compatibility with other radio sources operating on the air, as well as means sensitive to radio emission and the mobile means for receiving the signal emitted by the transmitting device is made in the form n, where n≥1, integer h layer converters repeaters for further transmission of the received signal in the second frequency range to n radio receivers.

 In this case, in a preferred embodiment, the first frequency range belongs to the range of 26-30 MHz, and the second frequency range belongs to the interval of 67-108 MHz.

In a preferred embodiment, the KARAOKE mobile system described above has a mobile wireless transmitter configured to transmit a modulated radio signal at a carrier frequency of a signal f ₀ belonging to the first band, and the means for receiving a signal comprises n separate carrier frequency transmitters, where n≥1 is an integer, the i-th (i-1, 2, ..., n) converter repeater is configured to receive the signal at the carrier frequency signal f ₀ and its subsequent transfer to a frequency-modulates vannogo radio signal at carrier frequency f _i, belonging to the second range, the converters repeaters arranged in n zones reliable reception of the signal transmitting apparatus, and means for converting the received radio signal into an acoustic signal is in the form n consumer radios capable of performing radio reception in a second range , other i-th radio receiver, where i-1, 2, ..., n, is tuned to the received frequency of the carrier of the radio signal f _i emitted by the i-th repeater-converter, and is located in close proximity to t him.

 Another particular case of such a system is the KARAOKE mobile system described above, in which the mobile wireless transmitting device is configured to transmit a near-field modulated electromagnetic signal, and the mobile means for receiving the signal emitted by the transmitting device is made in the form n, where n≥1, an integer, near-field electromagnetic transducers connected to respective n electro-acoustic transducers-amplifiers.

 Such a system uses a component of the electromagnetic field, which is detected only at distances commensurate with the dimensions of the antennas and / or elements that create magnetic and / or electric fields in the surrounding space. It is important to note that the indicated component of the electromagnetic field (regardless of the frequency range) is not an electromagnetic wave: it decreases with distance according to the same law as a constant or slowly changing field, therefore this component does not interfere with broadcasting, even if the frequency of this component belongs to the range of radio waves allocated for broadcasting and / or intercom. The interaction between the "transmitter" and the "receiver" in such a system is carried out according to the laws of electromagnetic and / or electrostatic induction; in this regard, such a system is in some sense intermediate between wired and wireless communication systems.

 Despite the fact that such a system is called a near-field electromagnetic signal transmission system, if desired, communication through such a system could be carried out at arbitrarily large distances by organizing a chain of relay receivers, which in this case behave like waveguide elements, then there is an electromagnetic signal that can be transmitted from one element to another "along the chain" in the absence of detectable radio emission in the surrounding space. Elements of such a “chain”, called transceiver receivers above, can be both passive (not containing energy sources) and active elements. In the case of passive elements, as an example, we can cite a chain of high-Q resonators, the "neighboring links" of which are located at distances from each other, although there are many large sizes of the resonators themselves, but such that the component of the near field is still detectable. Then, no matter how small the coefficient of electromagnetic coupling of these elements to each other, it is not difficult to show by choosing the quality factor of these resonators high enough and tuning them into resonance, it is possible to obtain a channel of electromagnetic energy along a chain of such resonators with an efficiency that is arbitrarily close to unity . But this means that almost all electromagnetic energy is distributed (theoretically, with ideal elements, without loss) along such a chain in the form of electromagnetic energy of the near field, without the emission of electromagnetic waves into the surrounding space.

 The mentioned elements of the chain can be located in any configuration (if the goal is not to transfer electromagnetic energy to the largest possible distance, but, for example, to cover the largest area), it is enough to ensure that the condition according to which any two elements of such a system are arbitrarily selected are connected between a signal of the near field either directly (for the case of adjacent links, elements), or through intermediate links, elements.

 In essence, such a technical solution allows for the exchange of information combining the advantages (in terms of mobility) of terrestrial radio communications and wired, cable communications (in terms of electromagnetic compatibility, directivity of transmission to a specific consumer, information security from unauthorized listening, access, etc. .).

 So, for the “sounding” of large rooms, halls, squares, instead of laying broadcast wires, it is enough to establish, both stationary and on moving objects, a lot of miniature, made in integral design, active resonators-repeaters, mainly, near field.

 At the same time, each user with a mobile receiver (including a regular household radio) located in the near zone of at least one of any of the above-mentioned resonator-repeaters will have access to the transmitted information, despite the fact that in general radio wave ether may not be there.

 To expand the functionality of the KARAOKE transmitting device, as well as to use previously developed and / or manufactured, or already in use KARAOKE transmitting devices that were manufactured without taking into account electromagnetic compatibility, or when legal obstacles arise for registering a radio source in the occupied frequency range, in the KARAOKE transmitter, an additional means of constructively blocking the signal transmission may be provided la in this (in the previously mentioned terminology, in the second) frequency range.

In view of the foregoing, the second subject of the present invention is a method for providing electromagnetic compatibility for a KARAOKE mobile system, according to which music data is sampled and decoded from a memory device with a replaceable cartridge for receiving a first signal, receiving and converting an acoustic signal using a microphone to obtain a second signal , processing the first and second signals, the formation of the resulting output electrical signal, the generation and radiation of a signal at a carrier frequency f ₀ belonging to the first range, which is dedicated for free use with limited radiation power, modulated by the resulting output electrical signal, for a given limited radiation power P ₁ , the reception of this radio signal in n different zones using n transceivers means a first type, conversion and re-emission of the signal by each of said receiving and transmitting means of the first type at frequency f _i, belonging to the second range, when m generality reradiation not more than ₁ kP, where k <0.1, independent of the re-reception of the signal in each i-th zone (i-1, 2, ..., n), at the carrier frequency f _i, i-m radio receiving means of the second type, and its conversion into an acoustic signal. In a preferred embodiment of the method of providing electromagnetic compatibility for the KARAOKE mobile system, the first frequency range belongs to the range of 26-30 MHz, and the second frequency range belongs to the interval of 67-108 MHz.

 In this case, as the i-th radio receiving means of the second type, a standard broadcasting receiver with a band including at least one of the bands 67-88 MHz and 88-108 MHz can be used.

In a preferred embodiment of the method, in each of the zones, the distance L _i between the respective said devices of the first and second types does not exceed the maximum length of their antennas.

 It is possible to transmit a signal from each i-th device of the first type to the corresponding i-th device of the second type by the electric and / or magnetic field of the near field.

 Moreover, devices of the first type can be made in such a way that radio emission (far zone) is suppressed in them.

 A third subject of the present invention is a mobile wireless transmitting device for a KARAOKE mobile system, comprising a housing adapted to conveniently hold, move and control the performer, inside or on which are located a microphone for receiving an input acoustic signal, a control panel, a microprocessor, a sound synthesizer associated with a microprocessor , music search tool with a decoder, a storage device connected via a multiplexer to an interface connector for connecting one of the many cartridges, made in the form of a lodgement or molds, means for convenient input and mounting on the housing of a cartridge connected via an interface, a device for converting and processing a signal from a microphone and a signal of reproduced musical accompaniment, means for generating a resulting output electrical signal and its subsequent transmission in the form of modulated radiation into the surrounding space, an additional decoder for interacting with the cartridge through the in interface configured to recognize a legal cartridge protected from unauthorized access by an authorized key identifying and encoding device with an access password to prevent the mobile wireless transmitting device from operating about an unauthorized cartridge or other storage device that does not have an authorized key encoding device with an access password.

 In the first preferred embodiment of the mobile wireless transmitter for the KARAOKE mobile system, the signal is transmitted to the surrounding space in the form of electromagnetic radiation in the optical range, which may include infrared, visible and ultraviolet radiation.

 In the second preferred embodiment of the mobile wireless transmitter for the KARAOKE mobile system, the signal is transmitted to the surrounding space in the form of ultrasonic acoustic radiation.

 In the third preferred embodiment of the mobile wireless transmitting device for the KARAOKE mobile system, the signal is transmitted to the surrounding space in the form of radio waves in a free allocated band, not occupied by broadcasting and service communication transmitters.

 Another possible embodiment of a wireless transmitting device for the KARAOKE mobile system is the use of an electric and / or magnetic field of the near field (antenna) with the possibility of suppressing radio emission.

 A fourth subject of the present invention is a cartridge for the KARAOKE mobile system, comprising a housing configured to be mounted on a lodgement (in mold) in the housing of the KARAOKE mobile transmission device, a cartridge interface connector for connecting to the KARAOKE mobile transmitter interface connector, and mounted on a mounted in the cartridge case of the printed circuit board in the form of integrated circuits, a read-only memory device for storing data representing musical works , and a key identifying and encoding device made in the form of an appropriately programmed microcontroller, connected to a read-only memory device and configured to interact with an additional KARAOKE mobile transmitting device decoder through an interface connector to prevent unauthorized access to data stored in read-only memory and the ability to automatically identify the cartridge means contained in the mobile om transmitting device KARAOKE to prevent information from entering into it from any cartridge or information storage device that does not belong to many authorized, legal cartridges.

 In the preferred embodiment, in the cartridge, the key encoding and identifying device is made in conjunction with the permanent storage device of the cartridge in the form of a secure data system with a password, which facilitates the exchange of data on the KARAOKE mobile transmitter associated with it, which contains an identical password in its additional decoder.

 A fifth subject of the present invention is a method for preventing the use of unauthorized (illegal, pirated) cartridges and other storage media in a KARAOKE mobile system with a KARAOKE legal mobile transmitter, according to which the KARAOKE mobile transmitter is provided with means for identifying the cartridge as belonging to an authorized plurality of legal cartridges, and means for blocking reception of data from the interface when an interface connection with an unauthorized one is detected information storage device, and all cartridges belonging to many authorized cartridges are equipped with a key encoding and identification device with an access password.

 A sixth subject of the present invention is a method for preventing unauthorized access, copying and use of data stored in a memory device of an authorized legal cartridge for the KARAOKE mobile system, according to which the KARAOKE mobile transmitter is equipped with an additional decoder configured to interact with the cartridge through an interface connector, and each of cartridges belonging to many authorized legal cartridges are provided with protection data, made in the form of a key identifying and encoding device, which is a microcontroller programmed with the ability to protect data stored in a permanent storage device of a legal cartridge from unauthorized access, as well as the possibility of issuing to the interface an identification code of the cartridge, according to which the data representing musical works, pre-packaged using password archiving methods, then encrypted using the code, known cartridge to the legal manufacturer of the cartridge, and in this form it is written to the permanent storage device of the cartridge, and the mentioned data are legally accessed using a system of interacting with each other through the interface of the additional decoder of the mobile transmitter KARAOKE and the key identification and encoding device of the cartridge, which provides direct access to the data after checking the coincidence of the key codes stored in the said additional decoder and the key encoding device cartridge.

 The cartridge for the KARAOKE mobile system can be equipped with a printed circuit board on which a permanent storage device is installed for storing data representing musical works, which is made in the form of a read-only memory chip (ROM), an interface connector and a key identifying and encoding device that can be made in the form of a microcontroller programmed with the ability to protect data stored in ROM, and issuing a cartridge identification code to the interface upon request password from its associated transmitting device. The cartridge may be provided with a housing in which the printed circuit board is mounted.

 Each cartridge may contain some specific type of music, for example, country or pop music, may be a collection of the most famous songs or individual songs of one or more singers.

 A mobile transmitting device for KARAOKE can be performed in a housing having a mold in which the interface output is output, for installation on a cradle of a cartridge, the casing of which is adapted for installation on this cradle. The interface of the interaction of the transmitting device with the cartridge can be made both via detachable contacts and non-contact, using optoelectronic pairs, inductive coupling, etc.

 The KARAOKE mobile system for performing musical works provides mixing the sound of the human voice and the selected musical accompaniment and transmitting the received signal to the receiving device, including a conventional radio receiver and amplification system.

 In this case, the reproduced musical accompaniment and the sound of a human voice can be stereo-processed.

 The device provides memorization of many songs and there is a microcontroller that allows the performer to control the song selection, rhythm and tempo, sound effects and volume level from where the artist is located.

 The device does not have restrictions on the location due to size or power, can be easily transported by one person and allows, in particular, to reproduce sound where there is a conventional radio receiver, such as a home stereo radio receiver, or a stereo radio receiver and amplifier, or a car stereo radio receiver, or portable a radio or a miniature "walk" receiver.

 The device provides the transmission of human voice and musical accompaniment to a house, car, portable or "walking" receiver with a power amplifier that provides the required level of mixed sound.

 When using an ultrasonic acoustic information channel, there are some features. Unlike electromagnetic radiation, the propagation time of which from the transmitting device to the receiving one is negligible and may not be taken into account when analyzing the operation of the KARAOKE system, the speed of ultrasound propagation under normal conditions is 340 m / s, which creates a delay in the received signal relative to the transmitted one. This delay may practically not be taken into account when the device is used in rooms of small sizes (volumes), for example, when used in a passenger car, as well as when working in open spaces when the receiving device is located at a small distance relative to the transmitter.

 However, when working in confined spaces of medium and large volumes (in halls, bars, restaurants, etc.), this signal delay must be taken into account. Taking into account the propagation of both direct and reflected ultrasonic signals, reverberation effects and an echo effect can be obtained, and, in contrast to the reverberation effect and an echo signal artificially created by electronic circuits, the acoustic effects that are natural for an ultrasonic channel depend on the measured dynamically the acoustics of the room, from the location and movement of both the transmitting and receiving devices, as well as from the presence and movement of other acoustically interacting objects, which creates "Presence effect", which can not be obtained artificially.

 Another effect characterizing the ultrasonic signal transmission channel is associated with the presence of absorption of ultrasonic radiation, which substantially depends on the frequency (approximately proportional to the square of the frequency).

 This property of ultrasonic radiation has so far been considered an obstacle to communication in air through an ultrasonic channel. However, in relation to the KARAOKE mobile system, the presence of attenuation during the propagation of ultrasound in air can be used as a positive property. First of all, in contrast to electromagnetic radiation, which includes radio waves, infrared radiation, visible light and ultraviolet radiation, which at the receiving site creates a background "exposure" from extraneous sources (interference, noise) due to the attenuation of ultrasonic radiation in the space surrounding a person, usually no ultrasonic radiation. Therefore, even a very weak ultrasonic signal can be confidently received with a high signal to noise ratio.

 The use of radio waves has the disadvantage that this signal spreads over long distances, much larger than necessary for the KARAOKE mobile system, and through the walls of the room, which is not always desirable. The executing user of the KARAOKE system may not want to be heard or have the ability to hear or receive a signal from outsiders. This can be important when working with professional performers and / or creators of musical works in the stage of creative search, rehearsals, preparation for the release of new musical works.

 When using an ultrasonic signal by choosing the frequency of the carrier signal, you can limit the radius of the possible action of the device, so that the system retains its qualities both in terms of mobility (cordlessness), and in terms of secrecy and audibility.

 At a carrier frequency of the ultrasonic signal of 100 kHz, the range of the device is limited by a distance of the order of 20-30 m, because at this frequency the signal is weakened due to absorption in air, 2 times at a distance between the transmitting and receiving devices of about 10 m. penetrates into neighboring rooms, since the difference in the densities of air and solid or liquid (i.e., condensed) media is so great that the air-liquid or air-solid interface is for ultrasound almost impenetrable border.

 On the other hand, due to the greater attenuation of ultrasound, compared with the sound of a frequency range audible by a person, it is easier to create a studio effect with sound absorbing coatings, and it remains possible to adjust the reverberation level by choosing the frequency of the carrier of the ultrasonic signal.

 If necessary, ultrasonic “sounding” of large halls, squares, etc., using high frequencies of ultrasound, can be used miniature active transponders-re-emitters, organized according to the same principles that were mentioned above in relation to the use of the electric and / or magnetic field near zones (antennas). This allows, despite the attenuation of ultrasound in the air, to organize the transmission of ultrasound at high frequencies and over long distances.

 When moving the artist with the transmitting device relative to the receiving device and relative to the room, the signal characteristic due to ultrasonic acoustics can change. This not only makes the sound more natural compared to the singer’s voice transmission from a radio microphone in the form of a radio signal or other electromagnetic radiation, which practically exclude the natural acoustics of the room, but also allows you to get new, adaptive, adjustable ultrasonic acoustic effects that are impossible or difficult to obtain in a fixed audible frequency range.

 Indeed, the claimed invention achieves the isolation between the perceived frequency of the sound signal and the frequency of the ultrasonic signal, which is actually a carrier of the perceived sound frequency. So, by the appropriate choice of the modulation method and parameters of the carrier ultrasonic signal, it is possible to achieve the desired pattern of timbre changes during the movement of the performer and listener during the performance of a musical work.

 An ultrasonic channel can be used both as a single (main) channel and as an additional to a radio and / or optical channel. In practice, any combination of these channels can be used (optical, ultrasonic, near-field transmission channel and radio channel). In this case, it is possible to obtain an additional effect due to the difference in the propagation times of the electromagnetic and ultrasonic signals, which depends on the distance between the transmitting and receiving devices.

 Measurement of the magnitude of this difference allows you to get a signal characterizing the removal of the receiver from the transmitter, which can be used as a control signal to further adjust the parameters of the received signal (timbre, reverb, echo, etc.).

 The meaning of such a joint application of two or more of the above-mentioned, several channels can be as follows.

 Firstly, to obtain the universality of a transmitting device, it is desirable to perform it multi-channel, since in some cases it may be desirable to use some advantages of certain channels of information transfer, and in others others. It may turn out that among the receiving devices there are "multi-channel" ones. Then there is the possibility of additional technical, artistic and emotional impact of the performer on the audience. So, the optical radiation source used in the optical communication channel can be easily made with an adjustable radiation pattern, which allows you to control the received signal by simply changing the orientation of the transmitting device, while using different channels, you can control different parameters of the received signals and in different ways different listeners. This gives the performer one more additional expressive means.

As for the frequencies of the ultrasonic signal, when transmitting a signal in air at ordinary atmospheric pressure, the dependence of the signal transmission range (which is conditionally determined by the attenuation of the signal due to absorption by 1000 times) on the carrier frequency is expressed by the following approximate dependence:
frequency wavelength range
1 MHz 300 μm 1 m
300 kHz 1 mm 10 m
100 kHz 3 mm 100 m
30 kHz 10 mm 1000 m
In this case, in the case when the ultrasonic channel is used as additional to the electromagnetic, the bandwidth of frequencies for it can be chosen much smaller, and this also reduces the carrier frequency of the ultrasonic signal.

 If the sound synthesizer is located on the receiving side, and the music data is transmitted in a compressed, packed, archived form, then the required bandwidth of the ultrasonic channel can be significantly reduced.

 Feedback messages can be received. An audio signal is emitted from the side of the signal receiver and this signal acoustically reaches the transmitting device, including the microphone mounted in it.

 Since the signal sent by the transmitting device is known (and it can be stored in the buffer memory), and the received signal can be separated from the input audio signal of the artist, it becomes possible to find the transformation that the signal underwent as a result of its propagation cycle: transmitter-receiver-transmitter, equip the receiving device with an integrated signal converter, which will allow to process (amplify or attenuate) the reflected signals. In particular, this makes it possible to increase the resolution in identifying a signal by the time of its arrival.

 The mobile transmitting device can be made small enough to be portable and easy to transport. A person can use the device wherever there is, in particular, a regular FM-FM receiver, whether in a car, at home or on the street, with a large portable or miniature "walk-through" radio. The device can use powerful amplifiers for homes, cars, large portable or miniature radios, or amplification systems to provide high-power output sound. Even without the use of cartridges, the transmitting device, due to its internal, internal ROM, can provide a choice of approximately 1200 songs.

 Reception can be carried out by various FM receivers, therefore one performance can be listened through one or several radio receivers or amplification systems in a house or other place so that many people with personal, mobile, portable, “walking” or car radios can listen to the performance. In addition, the amplification of two or more systems may be connected.

 The microcontroller in the transmitting device provides the performer with the opportunity to fully control the sound generated at its location and significantly improve the quality of performance.

In addition, with a detailed description of the invention with reference to the drawings, this is done in relation to a preferred embodiment.

 It is understood that various changes and modifications of the described embodiment may be made within the scope and spirit of the invention, as defined by the claims.

 In the present invention, the memory for storing musical accompaniment data, a controller and a microphone are combined into a single mobile stand-alone portable device.

 In FIG. 2 schematically illustrates a KARAOKE system using a device in accordance with the present invention. The device 70 comprises a microphone 71, a controller unit 72, and a transmitter unit 73. The device is used with an FM receiver 74 consisting of a receiver unit 75 and speakers 76 to generate an audio output signal from a signal generated by the KARAOKE system 70. The signal 77 is preferably an FM -signal, which is issued by the device 70 and transmitted to the FM receiver 74. The FM receiver 74 may be a portable radio, a home or car stereo, or any other device that receives an FM signal and plays it through one and Do wear to speakers.

 Most conventional receiving systems contain a powerful amplifier. Although frequency modulation is preferable, it is also possible to transmit and receive signals of other types of modulation, not necessarily in the FM-4M band. The system configuration shown in FIG. 2, allows easy transportation of the KARAOKE system 70, does not require numerous wired connections and has no power restrictions.

 The FM receiver 74 may be small-sized, such as a portable radio receiver, with the KARAOKE device 70 being not limited to using only one receiving device. Thus, it is possible to transfer the device 70 from a car to a car or from house to house and use the system wherever there is an FM receiver.

 In FIG. 3 shows the appearance of the design of the KARAOKE system 70 with some controls. Shown is a microphone 71, a control panel 80 having a matrix of switches 2, a display panel 7 and additional toggle switches 81. The transmitter 73 is mounted at the base of the KARAOKE device 70. The control panel 80 and additional toggle switches 81 allow the user to select the accompaniment and change the acoustic characteristics of the signal, as described below.

 In accordance with FIG. 4, device 70 consists of two parts — a device for reproducing sound accompaniment and a frequency modulator.

 The audio accompaniment reproducing device comprises a ROM unit 1, a matrix of switches 2, a microprocessor 4, a memory 5, a display panel 7, a multiplexer 8, a stereo audio signal controller 11, and amplifiers 12 and 12a.

 Various melodies of musical accompaniment with the corresponding numbers of names are stored in the ROM unit 1 in the form of digital signals.

 The memory array is designed so that it can grow as much as required.

 The input signals from the matrix of switches 2, which are user-selected song numbers, and high-frequency synchronization pulses from the oscillator 3 with quartz stabilization are fed to the microprocessor 4, which performs general control of the system in accordance with the program stored in its internal memory. The program sends the music data corresponding to the selected number to memory 5, which is a random-accessed static memory. The microprocessor 4 also controls the output of music data from the ROM 1 by means of a multiplexer 8, a D-trigger 9 and a decoder 10.

 In addition, the microprocessor 4 outputs information about the functional state of the system to the display panel 7 through the control device 6 to the liquid crystal screen, and also provides the transmission of reproduced accompaniment musical signals to the stereo audio signal controller 11 for amplification by amplifiers 12 and 12a.

The frequency modulator unit of device 70 contains an external
input 13, internal microphone 15 (corresponding to microphone 71 in FIG. 3), voltage amplifiers 14 and 16, frequency filter 17, tone controller 18, echo generator 19, radio frequency (RF) modulator 20, gain controller 21, noise reduction filter 22 , power supply 23 and antenna 24.

 The audio signal from the external input 13, which may be an external microphone, or from the internal microphone 15 is fed to amplifiers 14 and 16, respectively. The amplified sound signal is then processed to give the signal the desired shape with the frequency filter 17 and to select a high or low tone by the tone collector 18. The sound signal after the tone controller is mixed with the echo signal from the echo generator 19, and the mixed sound signal is supplied to the RF a modulator 20, which converts it into a radio frequency signal. This RF signal is a normal frequency modulated signal. The aforementioned amplified audio signal is further adjusted by the gain controller 21 to improve its differential amplification and differential phase, with subsequent increase in the signal-to-noise ratio using filter 22 and to reduce the noise present in the signal. The signal with reduced noise is then supplied to the modulator 20 for combining with a signal representing a speech audio signal.

 The adjustable input audio signals and the reproduced musical accompaniment signal from the amplifiers 12 and 12a are simultaneously supplied to the RF modulator 20, and the output frequency-modulated signal transmitting the sound of a human voice and musical accompaniment is transmitted through the antenna 24 to conventional FM receivers.

 In FIG. 5 shows in more detail the reproduction scheme of the sound accompaniment of FIG. 4. The ROM unit 1 for storing digitally musical accompaniment signals and their corresponding numbers has an additional ROM unit 1a connected to an external connector 1b, allowing to increase such memory arrays. Using external plug-in memory units, in addition to the internal one, allows you to have access to the maximum possible number of musical accompaniments.

 ROM blocks can be stored separately from KARAOKE equipment and connected to the system separately, which allows you to choose memory blocks in accordance with your individual taste.

 Switch matrix 2 has keys with numbers from 0 to 9 to select the desired melody number, SW1 keys to control the rhythm and tempo, SW2 knob to change the musical tone, SW3 knob to accelerate or slow down the tempo, and SW4 to enhance and weaken the musical tone to the desired value during melody playback in case the corresponding keys SW1 and SW2 are on.

 The matrix of switches 2 also contains the reset key SW5 to restore the normal or initial state of the system when there are any difficulties in operation or in case of an error in choosing a key; continue operation key SW6 for continuous playback of the musical accompaniment stored in the ROM unit without additionally selecting a song number; selection key SW7 of the ROM unit for selecting any external ROM units when connected to the external connector 1b; the SW8 key, necessary to achieve the echo effect for the voice signal from the microphone, the start key SW9 to turn on the selected musical accompaniment; the stop key SW2D, which interrupts the reproduction of the melody for changing the song number, and the power key SW11 for supplying power to the system from the power source 23, which is powered, for example, from the internal battery.

 The input signal "from the matrix of switches 2 and the synchronizing pulses from the oscillator 3 with quartz stabilization are supplied to the microprocessor 4, which performs the overall control of the system in accordance with the program, which will be described below. The microprocessor 4 stores in memory 5 data corresponding to the selected musical accompaniment. B at the same time, the microprocessor 4 provides an output signal in the form of data transmitted sequentially, the clock signal and the liquid crystal loading screen signal to the device is controlled I such screen 6 via internal data bus and generates the code of functional status for seven-segment display 7 panel.

 When microprocessor 4 selects specific data, for example, musical accompaniment, from data stored in ROM 1 or 1a via the internal bus, the selected data is written or read from memory 5 via multiplexer 8 and decoder 10, while the output is read through D -trigger 9. Output signals, such as the chip selection signals YM1, YM2 from the decoder 10, and the read and write signals RD3, WR4 from the multiplexer 8 are supplied to the stereo signal controller 11 via the internal data bus. The stereo sound source controller 11 comprises two integrated circuits (ICs) of the melody 11a and 11b, an oscillator 11c, and two digital-to-analog converters (DACs) 11d and 11e. In response to the input signal, the melody integrated circuits 11a and 11b generate stereo rhythm signals based on the music data reproduced from the ROM unit 1 or 1a. The output signals from the IC tunes 11a and 11b are converted by the corresponding DAC to obtain an analog signal corresponding to the original musical accompaniment. The output signals from each DAC 11d, 11e are amplified by an amplifier 12, 12a, as required for the RF modulator 20.

 In FIG. 6 is a detailed electrical diagram of a frequency modulator unit of device 70. Sound signals from an external input 13 connected to an external microphone or from an internal microphone 15 are supplied to voltage amplifiers 14, 16 on transistors Q1, Q2, respectively, to achieve the desired signal level. Each amplified audio input signal is filtered by transistors Q3, Q4 of the frequency filter 17 and acquires the necessary shape through the controller 18 on the transistor Q5, resistors R2, R3 and capacitors C2, C3.

 An audio input signal selectively generated by its high or low tone level is supplied to an RF modulator 20, which also receives the output signal of the echo generator 19. The echo generator 19 is configured in the usual manner, includes a clock generator 19a and a bridge circuit 19b, and generates an echo sound, delaying the low level output signal by a time constant determined by the variable resistor VR1, capacitor C1 and resistor R1.

 An echo sound is issued only if the SW8 key of the switch matrix 2 is pressed.

 The input amplified sound signal from voltage amplifiers 14 and 16 is regulated by a gain controller 21, consisting of a divider on resistors R4 and R5, to improve the characteristics of the differential gain and phase. The signal-to-noise ratio is increased by removing the noise component by the noise reduction filter 22, which is built on the resistors and capacitors R6, C4 and R7, C5 shown in FIG. 6. The processed sound signal is mixed with the echo signal provided by the echo generator 19, and the adjusted input sound signal and the reproduced music accompaniment signal from the amplifiers 12 and 12a are simultaneously supplied to the RF modulator 20, which converts the input sound signal to a radio frequency modulated frequency modulation, using an inductor L1 and a transistor Q6. The radio frequency signal is then finely tuned in the RF modulator 20 by an L2 coil and a Q7 transistor. Finally, an output frequency-modulated signal transmitting the sound of a singer’s voice and musical accompaniment can be transmitted through an antenna 24 and received by an FM receiver tuned to the output frequency of the device.

In this device, the voltage from the internal battery (for example, 9B) is supplied directly to the audio frequency amplifier and RF modulator, and the operating voltage (V _cc ) of 5 V is supplied to other units through the regulator chip in the power source 23, if the power switch SW11 is on on the matrix of switches 2.

In FIG. 7 is a flowchart of the microprocessor 4 shown in FIG. 4, to perform control functions in accordance with this invention. At step 100, it is determined whether the supply voltage is 9 V. If the power switch SW1 in step 102 is determined to be “on”, then the microprocessor 4 in step 103 outputs LCD DATA signals (data to the liquid crystal screen), the LCD CLK clock signal, the LCD LDP boot signal to the LCD control device 6 and displays “1” on the display panel 7, which corresponds to the normal supply voltage V _cc supplied from the power source 23.

 To use the microphone and the RF signal control, additional operations are required. To this end, at step 104, the remote FM receiver and amplifiers are turned on, the desired frequency is tuned at step 105 (for example, 98.1 + 1 MHz or 100 + 1 MHz) and the necessary amplifiers are adjusted at step 106. If at step 107 an input numeric code is received from the matrix of switches 2 corresponding to the desired song number, then multiplexer 8 selects one of the ROM blocks 1 or 1a in accordance with the position of switch SW7, and the corresponding stored data is called up via the bus. In step 18, it is determined whether the play key SW9 is turned on, and if it is turned on, the stored music data in step 109 is read out by selective locking by the D-trigger 9.

 The digital data read from the ROM blocks 1 or 1a is supplied to the melody ICs 11a, 11b of the stereo signal controller 11 through the multiplexer 8. The melody ICs 11a, 11b generate rhythm stereo signals based on the output signal of the generator 11c supplied to the corresponding DACs 11b, 11e, in which the data is sampled and converted to analog signals. The analog output signals are transmitted to amplifiers 12a, 12b, and the amplified analog musical accompaniment signals at 110 are supplied to the RF modulator 20 to convert them to FM radio signals, and then to the antenna 24.

 In the next step 111, it is determined whether there is an audio signal at the speech input from an external or internal microphone. If the user wishes to play back the musical accompaniment read from the device memory, then the input audio signal is mixed with the musical accompaniment signal at step 112.

 If the stop key SW10 on the switch matrix 2 is pressed during the above procedure, at step 113, then the playback of the selected musical accompaniment is interrupted at step 114. If at step 115 you want to change the musical tone of the accompaniment and the tuning switch SW2 is on, then the tone is adjusted to the desired desired value while playing music. At step 116, the switches SW3 and SW4 are adjusted up or down to select the desired level.

 If at step 117, the rhythm control switch SW1 is activated, then at step 118, it is possible to speed up or slow down the rhythm by pressing the corresponding keys steadily once again as necessary. In accordance with the described operations to adjust the tone and rhythm of the music, the microprocessor 4 displays the numerical values of the adjustments on the display panel 7.

 If it is determined at step 119 that the SW8 key is turned on to receive the echo effect from the voice entering the microphone, then the sound echo from the echo generator 19 is supplied to the RF modulator 20 and mixed with the demodulated signal at step 120. At step 121, if it is detected that the ROM block selection key SW7 is pressed and an additional ROM block 1a is connected, then the corresponding ROM block is selected by the multiplexer 8 in step 122, and the desired musical accompaniment is selected. Each ROM block may contain some specific type of music; There are many options for the contents of ROM blocks.

 If the play continuation key SW6 is turned on at step 123, then the subsequent playback of the musical accompaniment stored in the ROM unit 1 or 1a is performed at step 124 without having to select a song number. The device 70 according to this invention can selectively process input audio signals containing voice and reproduced musical accompaniment to obtain a mixed signal and transmit it via the FM channel in the form of a stereo signal. This design of a stand-alone KARAOKE device, which is used with a conventional FM receiver, also allows portable use in a room, on the street or in a vehicle, wherever an FM receiver can be located. The user can even play songs accompanied by music while walking on the street and use a portable radio to receive transmitted signals.

 In FIG. 8 shows a second embodiment of the frequency modulator shown in FIG. 6. The frequency modulator block of FIG. 8 contains an echo generator 30, a tone controller 31, a gain controller 33, a noise reduction filter 34, an RF modulator 35, and an antenna 36. The echo generator 30 includes a bridge device 30a connected to resistors R11, R12 and capacitors C11, C12 for generating a sound echo delayed by a time constant determined by the values of R11, R12 and C11, C12, and to amplify the sound echo through a push-pull circuit on transistors Q11 and Q12.

 The output echo is supplied to the tone controller 31 to control the gain of the transistor Q13 by adjusting the variable resistor VR11, and to mix with the sound the voice coming from the input terminals 32 and 32a of the stereo microphone. The sound output echo is also controlled by transistor Q14 relative to the level of the input voice signal.

 The input audio signal is mixed with the echo, if necessary, and fed to the gain controller 33, which contains the operational amplifier OP1, which has a feedback circuit on the resistor R13 and capacitor C13, which regulates the amplitude of the variable resistor VR2, and a filter consisting of resistors R14, R15 and capacitors C14, C15. The amplified input signal processed by the OP1 operational amplifier maintains the output signal at the desired level by adjusting the variable resistor VR2. The input audio signal is then separated by a filter into stereo audio signals MIC-L and MIC-R.

 The stereo audio signals MIC-L and MIC-R are mixed with reproduced musical accompaniment signals IN-L and IN-R, respectively, which pass through a noise reduction filter composed of resistors R16, R17, and capacitors C16, C17. The mixed signal is amplified in the microcircuit of the audio frequency amplifier 34a and is converted by the RF modulator 35 and precisely tuned by the radio frequency generated by the generator containing the inductance L11 and transistor Q15.

Thus, a modulated output signal containing the sound of a human voice and musical accompaniment can be transmitted through the antenna 36 and received by conventional FM receivers in the radius of the radio reception. The supply voltage from an internal source, in this example, a 9 V battery, is supplied directly to the audio amplifier and frequency modulator, and by means of a voltage regulator (not shown) in the power supply, the operating voltage of 5 V (V _cc ) is supplied to other circuits, in the case of if the power switch SW11 in the matrix of switches 2 is turned on.

 The above description illustrates the principles of the invention. Specialists in the art can create numerous systems and devices that, although not exactly the same as described above, but embody the principles of the invention and therefore are within the scope and essence of the invention.

 When using equivalent integrated circuits for each functional unit, the size of the system is significantly reduced, which increases the degree of system mobility.

 Thanks to the use of an additional decoder in the KARAOKE mobile system for interacting with the cartridge through the interface connector and the use of a key identification and encoding device associated with the ROM in the cartridge, the possibility of unauthorized access to data stored in the permanent storage device is prevented, and the KARAOKE system is prevented from functioning unauthorized, illegal cartridge.
